Hey everybody.
I just purchased a new P99c AS in 9mm last week. Today I shot 150 rounds of 115 grain WWB and 50 rounds of 124 grain WWB. Five separate times, usually around the fifth or sixth round per magazine, I had a failure to fire twice with the 124 grain and three times with the 115. The gun would reset to full DA mode and then I pulled again and it fired. Why is this? I also shot my SIG 228 today and had no problems at all.

Thanks,

A-man

Can't say what the problem is...if it is a NIB gun maybe it needs cleaning around the striker...to make sure no grease or dirt is keeping the striker from moving forward.

Break in is usually around 500 rds so don't give up yet...there are some knowledgeable guys on this forum and I am sure that they can give you more advice...

Worst scenario is that you call WaltherAmerica…they can give you some advice. I will say this that the P99 is too good of a gun for it to be anything major that cannot be worked out with a little help. I think you will find that the P99 is just as good as your 228, no kidding.

Be patient! your new pistol needs a break-in period. I would suggest removing the striker assembly; once removed, clean it, apply a light coat of oil on the spring coils. possibly there may have been some residue present on the firing pin of the striker assembly. You will be able to better ascertain once it is removed.

Do not oil striker assemblies. Oil/grease will attract dirt and residue. Old oil/grease can gum and congeal into a semi-solid mess.

Disassemble the slide and de-grease the striker assembly with Gunscrubber or a similar product. Re-assemble and shoot.

Thanks for that info - I may disassemble mine next year - and I figured I would lightly oil it. Thanks for the advice

Great advice from Blueiron........... as a general rule never oil striker assemblies

However, if you are constantly taking you gun from an airconditioned environment and then back into a hot humid car etc.

You might want to coat the striker with one drop of Break-Free CLP and then dry with a clean patch. CLP is a wonderful cleaner/conditioner/lubricator that will not gum and can disolve carbon deposits on contact while staying very fluid. The amount you will leave on the striker will just be enough to coat the metal spring to prevent corrosion from moisture build up. Corrosion can stop spring function as well as dirt & gum.

Each senerio requires a different course of care for your weapon depending on the environment -- but generally speaking keep those strikers clean and dry !
